Application filed May 2, 1921, Serial No. 466,173. Renewed September 10, 1925.

17 'o all wiz-0m it may concern.:

Be it known that we, GUs'rAv Ecrorr and HARRY P. BENNER, both citizens of the United States, residing in the city of Ch1 5 cago, county of Cook, and State of Illinois,

have invented certain new and useful Improvements in Dephlegmators, of whichthe following is a specification. This invention relates tol dephlegmators and refers more particularly to a sectional dephlegmator which has a number of removable stages adapted to be interchanged and adjusted in a manner that the quality of i vapors and the character of the distillate is readily controlled.

Among the salient objects of the invention are to provide an apparatus comprising a dephlegmator having'a series of successive stages divided therein by means of shelf-like perforated plates through which the vapors are directed in their travel through the dephlegmator; to provide a dephlegmator or rectifier in which the plates are not only removable butare built up in sections so that the porosity of the individual plates or dividing partitions between the zones may beregulated by inserting sections having a greater or less number of apertures therethrough; thereby facilitating or obstructing the passage of the vapors through the length of the condenser; to provide an apparatus which permits the drawing off of distillate from the different zones which increases the capacity as there is no substantial accumulation of liquid condensate in the structure.;

to provide a dephlegmator that may be readily cleaned and one that is positive in operation.,

In the drawings: v Fig. 1 is a side elevationalview of an oil cracking apparatus having the dephlegmator mounted above the expansion chamber.

Fig. 2 is an enlarged sectional view of the de hlegmator.

ig. 3 is a detail of the means for positioning the partition plates on the central shaft.

Fig. 4 is a plan view of one ofthe skeleton frames for supporting the partition shell.

Fig. 5 is a -face view of one of the uppermost partition plates.

Fig. 6 is a face view of one of the lower partitions showing the increased number of apertures therein.

Referring particularly to the drawings, describing brieliy the use of the dephlegmator in connection with the oil cracking apparatus shown, the raw oil is introduced vfrom any suitable source through the inlet line 1, controlled by a valve 2 and is charged to the heating tubes 3 mounted in the furnace 4 by means of the charging pump 5 and a charging line 6 regulated by a valve 7. The oil, after being heated to a vcracking temperature in the heating tubes is directed through the transfer line 8 to the expansion chamber 9 to which zone the' vaporization is restricted. The vapors released from thel oil rise to the dephlegmator 10 while the heavier residual liquid is drawn off through residuum line 11, controlled by a valve 12 and directed to storage or toother desired means for treatment. The dephlegmator 10 comprises an outer shell 13 which'is closed at both'ends by means of closure caps 14. To the upper closure member is fastened 'a shaft or rod 15 extending down through the most partitions are similar to those shown Y in Fig. 5, where the number of apertures or holesthrouofh the partitions are greatly decreased. esides the controlling of the speed and volume of the vapors which pass up to the dephlegmator, by means of thenumber of apertures in the plates, an additional control may be had by the positioning of the plates at predetermined intervals on the shaft, by means of theset screws 17, which are adapted to set into the Anotches 16 in the shaft. The dephlegmator has also two removable clean out plates 21, and liquid drawoff lines 22, controlled by valves 23 spaced at intervals throughout its length.

Vapors generated in the vaporizing chamber rise 'into the lower part of the dephlegmator and pass through the apertures in the plates positioned at intervals throughout the length of the dephlegmator, the condensate being drawn off through the lines 22, which communicate with a verticaldrawotl' line 24 connecting with the lower drawoi 25 controlled by a valve 26. The lower drawof leads to a water condenser 2T` from which the condensed distillate is collected in a receiver 2S which is'equipped with a liquid drawoff line 29 controlled byia valve 30 and a pressure relief pipe 31 regulated by a valve 32. In operating a cracking system with the above described dephleg'mator, it is under-- stood that --with different types'of oil and under different conditions of treatment, the positioning of the partitions in the dephlegmator and the number of partitions used, besides the type of partition will vary. In some cases, where a large volume of vapors are to be treated, it may be necessary to use the baille plates having a large number of apertures throughout the length of thede- P legmator and in other eases. the perfo-V rated bailes with the largev number of apertures will only be used in the lower portion of. the dephlegmator. In addition to the conti-ol, the character of the battles, and positioning of the battles is of importance.

We claim as our invention:

l. A dephlegmator for an oil cracking system, comprising a chamber having vapor inlet and outlet, ports and a plurality of battle lpartitions dividing the chamber into stages adapted to obstruct the'travel of the vapors, means for. drawing ott the condensate at various stages in thevapors travel, ihe position of said baiiles relative to one another being manually variable, and adjustable means for holding .said baties in their different positions of adjustment.

2. A dephlegmator, comprising a casing havinga vapor inletand a vapor outlet, a central standard disposed within said casing, a plurality of perforated plates mounted on said standard adapted to obstruct the travel of vapors through the dephlegmator, and manually adjustable means connected with each plate t`or maintaining the plates in different positions of adjustment relative to' one another. y

3. A dephlegmator, comprising a casing having a. vapor-inlet and a vapor outlet` a central standard disposed within said casing, a plurality of perforated plates mounted on said standard adapted to obstruct the travel of vapors through the dephlegmator, and manually adjustable means connected with each plate for maintaining the plates in different positions of adjustment relative to one another, said means including a collar and a retaining p-in threaded therein for each baille, in .combination with a plurality of sockets inl said standardv disposed in spaced relation and adapted to -receive said retaining pins.

4. A dephlegmator comprising a casing and central standard disposed therein, a plurality of partitions in said casing, and means for adjustably supporting said partitions on said standard 'whereby the positions thereon `may be manually varied, said means including' an adjustable element conueeted with each partition and adapted to cooperate with sockets in said standard.

5. A dephlegmator, comprising a casing having a vapor inlet and a vapor outlet, a plurality of partitions in said casing, means for adjustably supporting said partitions within said casing whereby the vertical positions of such partitions may be manually varied, said means including an adjustable element associated with each partition for securing the partitions in adjusted positions.

6. A dephlegmator, comprising a casing, having a vapor inlet and a vapor o utlet, a plurality Aof vertically1 *spaced perforated plates mounted within said casing to obstruct the `travel of vapors through the dephlegmator, manually adjustable means associated with each plate for maintaining the plates in any desired vertical positions of adjustment relative to one another.
